vApplication filed July 28, 1904. Serial No. 218,492.

To ZZ lc/iom t mag/concern Be it known that I. Giioncii H. UNDER- iiiLL,a citizen of the llnited States, residing at Boston, in the county ofSuffolk and State of Massachusetts. have invented an Improvement inSound Reproducing or Recording Machines, of which the followingdescription, in connection with the accom- .ianying drawings, is aspecification, like Aetters on the drawings representing like parts.

My invention consists in improvements in sound-reproducing or recordingmachines, being particularly, though not exclusively, concerned withmachines employing a plurality of records which are brought successivelyinto operative relation with the sound-recording or reproducingmechanism.

-I have herein illustrated one specific einbodiinent of my invention asapplied to a sound-reproducing or recording machine employing a feedingmechanism by means of which the reco-rds are singly and automaticallytransferred from a traveling inagaziue or holder into operative relationwith the sound-reproducing mechanism of the machine. Subsequently. afterreproduction of an individual record. the latter is then automaticallywithdrawn from its operative position upon the machine and replaced inthel holder, which then advances to .bring a. fresh record adjacent thelmachine. The new record is then automatically transferi'ed to themachine, the stylus mechanism restored to its initial position, and theoperations of the machine, which, (hiring the interval of feeding therecords on and off the holder have been,suspended, are repeated asdescribed.

My invention will be best understood from the following description,when taken in connection with the accompanying illustration. of the onespecific embodiment thereof b v which I have herein illustrated thesame, while .its scope will be more particularly pointed out in theappended claims.

In the drawings. Figure l is a plan view of the machine by which I haveherein illustrated inyinvention; Fig. 2 is a sectional elevation 'of therecord feeding mechanism taken on the line 2 2 -in Fig. 3: Fig. 3 is asectional elevation looking toward the' right. and on the line 3--3 inFig. 2,; Fig. ll

is a section on the line Jf-l in Fig. 5 looking-toward the right andshowing `the feeding carriages; Fig. 5 is a planview on an enlargedscale of the feeding mechanism with the traveling carrier removed; Fig.6 is an elevation, partly diagrammatic, showing the tilting shelf andthe control thereof; Fig. 7 is an enlarged cross sectional view v to thethreaded shaft a', the latter beingsuitably journaled upon the frame c2of the machine and adapted to rotate the support with its record, as isusual, in operative relation to the sound-recording or reproducing'mechanism The cylinder overhangs the frame and the ball bearing af, thelat-- ter being provided, in the absence 0f the usual centering screw atthe outer end of the cylinder, to center the saine by movement. of thescrew c". The sound box, stylus and connected parts may be ofv anydesired or ordinary construction, and are therefore not' herein shown,but are carried 'by the arm a3, secured to the sleeve a4, slidable onthe stationary guiding shaft a5, the latter beingl parallel with therecord support.. Secured to one end of the sleeve a? (Fig. v'7) is anarm c, carrying the nut a", which, during the operation of the machine,is adapted to engage With the comparatively ne threads upon the shaft aand cause the travel of the stylus in contact with the record from theinitial end (left-hand in Fig. l) of the cylinder to'the opposite endthereof, the usual rotary motion being imparted to the shaft a and therecord through the driving belt (1.8 connected with any suitablephonograph motor, such for example, as the electric motor A indicated inFig. 1 and diagrammatically in Figs. 6 and 9.

During the tra-vel of the stylus, the

threaded, adjustable, electrically connected points 7) (Figs. l, 6 and7), carried by, but insulated from, the overhanging end of the 'arm a3,are caused to contact with the tilting shelf b', hinged to the frame a2of the like material, for the separate phonograph and to bridge anelectrical circuit between the two contacts bps (Fig. 6) upon the faceof the shelf b when the desired limit of stylus travel has been reached.rlhe shelf b rests upon the cam lever b4 and, during recording' orreproduction, is in the dotted line position Figs. 5 and 6. Thecompletion of the circuit referred to, however, causes, as will be morefully described, energization of the magnet b5 and the movement of thecam lever b4 to the full-line position shown, resulting in lifting theshelf b into the position also shown in full lines. This raises the arm0:3, Withdraws the stylus from the record and the nut a?v from thefeeding screw a causing the simultaneous engagement of the nut a?, alsoconnected to the sleeve a4, with the coarse threaded return feed screw0,10. After the lapse of an interval, during which the phonograph motorstops and the feeding mechanism acts to substitute a fresh record forthe one already on the machine in a manner hereinafter to be described,the phonograph motor again starts and causes the return of the stylus toits initial position through rotation of the screw am, which is alsoconnected to be drivenby the belt as, as shown in Fig. l. The shape ofthe cam lever 6* is such that it naturally remains in the full-lineposition shown in Figs. 5 and 6, after the points b have left thecontacts 3 and the magnet b4 has become deenergized, until continuedstylus travel causes the points to bridge the contacts b at the oppositeend of the shelf b', acting thereby to energize themagnet bl and throwthe lever b4 into the dotted-line position shown, dropping the shelf andthe soundreproducing mechanism into its normal or operative position andbringing the stylus into contact with the new record. i

Referring more particularly to Figs. 1 and 3, I have herein provided arecord magazine or holder C to hold one or any number of records r andfrom which the said records may be withdrawn and placed upon the recordsupport a. rlhe form andconstruction of such holder may be widely variedand obviously will be modified to suit -the shape, type and constructionboth of thel machine and the records employed, and my invention in thisrespect is in no wise limited. I have, however", herein shown the holderC to consist of a rectangular tray divided by parallel walls into anumber of compartments, herein seven, in which hthe separated recordsrest, suitable means being provided, such as thelining c, of felt orcompartments, to prevent injury to the surface of the records. Securedto the bottom of the holder are parallel tubular shoes c which areadapted to slide within suitable stationary, semi-tubular guides c2secured to the insalate top of the frame D of the feeding mechanism, thelatter being removably connected to the phonograph frame a2 in such aposition that movement of the record holder C upon the frame of thefeeding mechanism permits any individual record to be brought into axialalinement with the supporting cylinder a, as is best shown in Figs. land 2. The travel of the holder C is effected by means of a rack c3,secured to the bottom thereof, and engaging with a. holder driving gearc4, the latter meshing with the holder driving pinion c5. The pinion c5rotates upon the shaft d, the latter being journaled at one end in thestationary u pr1ght support CZ and at the opposite end in the bracketd2. Looselyh mounted on the shaft d, both to rotate and slide thereon,is the main driving gear c, driven by the broad faced intermeshing motorpinion e', the latter being driven by the feeding motor Fl, which isindicated in dotted lines, and is preferably electric. rlhe slidingdriving gear c is provided at one side 'with clutch teeth e2, adapted toengage with corresponding teeth upon the holder driving pinion c5,thereby to drive the latter, and also at the opposite side with clutchteeth e3 to clutch and drive the clutch member Z3 secured to the shaftci, whenthe said gear is thrown to the position shown in Fig. 5. rlheposition of the driving gear e is controlled by the shifting lever e4,which is held normally in the position shown in Fig. 5 by the tensionspring e5, but, being connected to the core e of the solenoid e7, isadapted, on energization of the latter, to be moved about its fulcrum todisengage the teeth es from the clutch member d3 and to engagethe teethe2 with the holder driving pinion c5. rlhe feed motor, therefore, whenin motion, will normally, during denergization of the magnet e, causerotation of the shaft al, through the clutch member cl3, but, uponenergi'zation of the said magnet and the subsequent clutching of thedriving gear e to the pinion c5, movement will be transmitted directly-to the latter to rotate the gear ct and, through the rack c3, cause'travel of the holder C.

.Depending from the bottom of the holder -(Fig. 3) is a series of lugs06, there being provided one to correspond to each of the recor.compartments, each lug being so locatedirelatively to its respectivecompartment as to bring the contained records in .substantially accuratealinement with the predetermined position. Where the ful cruming pin fpasses through the finger f the latter is slotted, as indicated in Fig.3, the bottom of the slot however, being normally held against the pin,as shown in Figs. 3 and 10, by means of the tension spring, f4, Securedbetween the fulcruming pin and a pin upon the lever. The bottom of thefinger f is loosely connected to the plunger f5 of the solenoid f6, sothat when the latter is energized, the plunger and the attached fingerare drawn downward and against the tension of the spring f4. The pointofthe linger then leaves the face of the lug c6, and, the pressure by thelug c against the finger being relieved, the latter is forced by aspring f7 away from the stop screw f3 and against the oppositelyarranged contact screw fs. When drawn downward by the solenoid, thelinger f remains in a substantially upright position and, ondenergization of the solenoid, rests with its tip against the bottom ofthe lug. The holder is now unlatched and may be advanced one step assoon as the driving gear e is clutched to the holder driving pinion c5.lVhen the holder moves, the linger, which is pulled upward against thebottoni of the lug c by the spring f4, is left in position to engagewith the succeeding lug and properly position the succeeding recordrelatively to the phonograph cylinder.

Referring more particularly to Figs. l, 2, 3 and 5, the mechanism whichI have herein illustrated for transferring the records from the holderto the machine, and vice versa, comprises the pusher arm g, one end ofwhich is secured to the traveling pusher carriage g. The arm has adouble bend to bring its other end'opposite to and adjacent the outeredges of the records carried by the holder C, where it is provided witha telescopic sleeve, g2, slidable upon the end of the arm g with amovement limited by the pin g4, acting within a slot upon the sleeve g2,there being a spring g5 located within the sleeve to provide `a yieldingconnection between the said arm g and the pusher foot gs, which issecured to the end of the sleeve q2. The tips of the pusher foot gs arein y`line with the edges of the record, as shown in Figs. l and 2, andare adapted to engage the same and push the record out of its tray andon to the supporting cylinder a, when the pusher carri-age g is moved'from right to left. To remove the record from Ithe cylinder and replaceit in its tray from Ythe holder, there is provided the puller arm, h,secured to the puller carriage, it, the said Varm having its endprojecting beyond the carriage it', in axial alinement with, andentering, the tubular end of the puller arm g. The opposite end of thepuller. arm h is bent upward and carries the semi-circular yoke h2,which lies adjacent the inner edges of that record in alinement with therecord cylinder. Vhen the record is forced upon the cylinder under theimpulse of the pusher arm, the puller carriage h', as will be more fullydescribed, is caused to advance with the pusher carriage g', and thepuller yoke passes beneath the cylinder a before the advancing record.After the record has been used, it is returned to the holder by oppositemovement of the feeding carriages g and L, which cause the puller yokeh2 to engage with the edge of the record and pull it of from thecylinder and into its tray on the holder into the position shown in Fig.2. The slotted guiding bracket F (Fig. 2) `assists in guiding therecords in their passage from the cylinder to the holder.

Referring now to the construction of the feeding carriages and moreparticularly to Figs. 3, 4 and 5, said carriages are adapted to slidelengthwise the feeding screws 97 and h3. The pusher screw `g7 is rotatedfromthe shaft d, the latter having (Fig. 5) the driving pinion d4'intermeshing with the intermediate gear (Z5, the latter engaging withthe gear ZG upon the pusher screw g?. The puller screw h3 is providedwith the gear h4 intermeshing with the gear g8 upon the pusher screw gand rotated thereby in a direction reverse to that of the pusher screwg?. The carriages present to each other closely fitting surfaces (Fig.5) so that they may travel as a unit, one carriage forcing the otherahead of it, -or they mayv undergo slight separation as will hereafterappear. The carriage g (FigQ.) is provided at its side with thefulcrumed arm g, carrying the nut g1, which may be swung into and out ofengagement with the pusher screw g7 through an opening in the side ofthe carriage by movement of the lever gg. rI'he latter is thrown to itsposition of engagement by contact with the stationary cam g, whichoccurs in the outer position of the carriage and as shown in Fig. 5, thespring g12 coperating with a notch 1n the side of the lever to retainthe lever and the nut in their engaging positions until the carriage hasreached the limit of its travel in the opposite direction, when thedisengaging cam g1g contacts with the opposite end of the leverv gf tocause the latter to withdraw the nut g1 from engagement with y(thescrew, in which position it is retained' by the said `spring 912. Uponthe puller-carriage It I have alsoprovided a lever h5 carrying a nutit", which is thrown intoland out of engagement with the screw h3' bycontact with the stationary cams L7 and its, respectively; the spring71.9 being also provided, and the several parts acting with respect tothe carriage L precisely, al-

though in reverse order, as the parts de-A diagrammatically,

shown in Fig. 5, the nut h6 is out of engagement and the nut g1@ 1nengagement with its feed screw, and subsequent rotation of the saidscrews will cause the travel of the vtwo carriages in a left-handeddirection (Fig. 5), the pusher carriage forcing the puller carriageahead of` it, until the opposite limit of travel has been reached, whenengagement of the levers gg and 7&5 with the cams g and if,respectively, will disengage the nut glo from the pusher feed screw g?and engage the nut LG with the puller feed screw 71.3, andvsubsequentrotation of the feed screws will obviously result in the return of thetwo carriages. In order to clear the pusher arm from the record afterthe latter has been seated upon its support and to permit the freerotation ofA the record thereafter without interference, at the inner orleft-hand end (Figs. 2 and of the pusher carriage travel, I haveprovided the plunger z' having a piston seated against the compressionspring 21 in the cylinder 3. The pusher carriage is provided with adepending arm gt which is adapted to engage with the end of the plungerz' before the record has been pushed t0 its seat and to compress thespring 2 before completion of carriage movement. At the moment the nutglo is withdrawn from the pusher screw g?, the carriage is forced backby the spring-pressed plunger t', clearing the pusher foot g from theend of the record. rIhe puller arm is cleared from thel record at eachadvance of the holder by a series of small projections i* at the side ofthe holder which force the puller arm into the position shown in Fig. 2.

The electrical controlling circuits, which, it will be understood, areshown in the several views, for the sake of clearness, largely will beexplained in connection with the description of the mode of operation ofthe machine which will now be given. Assuming that the traveling holderis in the position shown in Fig. l and that the first of the records isto be placed upon the machine, the feeding carriages g and 71, and

'the stylus carrying arm a3 will also be in the position shown in Fig.l, said stylus carrying arm having previously been raised into itsinoperative position, Vready for return, as shown in Fig. 7. Thephonograph motor A is now at rest, for its circuit y' (Fig. 9)

passes throughy two insulated contact fingers j, which,

(Fig. 5) are adjustably secured upon the frame D of the feeding'mechanism, and at the left-hand end thereof as viewed in Fig. 5. withinthe path of the contact blade jg, the latter being carried upon thepuller carriage I/ and adapted to bridge the said contacts, andtherefore energize and start the phonograph motor, only when the saidcarriage is at its extreme limit of travel opposite to that shown inFig. 5.

The feeding motor E has one of its poles connected (Figs. 5 and 8) bymeans of a conductor c throughv a suitable circuit closing device 7c',herein a hand-operated switch, with a source of electro-motive force B.The other pole of the motor is connected to the conductor 7a2 in serieswith the contacts b3 upon the tilting shelf Z1 and the solenoid b5,which operates to raise the said shelf. Thus, it will be seen that thefeeding motor circuit may be broken either at the contacts b3 or theswitch c, the former being now closed on account of the position ofthearmv a3. As soon as the main controlling switch c is closed, the feedingmotor immediately starts up and causes rotationy of the feeding screws97 and 7b3. The pusher carriagey being 4in engagement with the pusherfeeding screw 97, the two carriages are caused to travel lengthwise thescrew Q7; the pusher foot gs meets the ends of the record shell, forcesit out of the holder and over the end of the adjacent cylinder; theyielding connection between the foot ge and the pusher arm g permittingthe latter to seat the record firmly upon the cylinder, without,however, the possibility of injury thereto,and permitting adaptation tovariations in the exact size 0f the records. When the record is firmlyseated upon the cylinder and the two car-riages reach their limit oftravel, as soon as disengagement of the nut g1@ occurs, the spring 2,which has been previously compressed by tlredepending arm gli upon thepusher carriage, throws the latter backward far enoughto clear the footgc from the cylinder. Simultaneously, the cam moves the lever h5 toengage the nut fr with the puller feeding screw h3. ln the meantime,however, and before reverse movementof the puller carriage L can takeplace, the switch blade jz mounted thereon has bridged thelcontacts jand caused the phonograph motor A to start, thus causing rotation of thereverse, phonograph feed screw L10 and the backward travel of the styluscarrying arm a3. The first movement of the latter causes the withdrawalof the contact points b from the contacts 3 and the interruption of thefeed motor circuit, as will be evident from Fig. 8, the adjustment ofthe parts being such as to start the phonograph motor and stop the feedmotor at substantially the same instant. The phonograph motor havingstarted, the stylus carrying arm returns to its initial position, wherebridging of the contacts 66 energizes the solenoid 67, drops the tiltingshelf 7)',

causes engagement between the stylus and l the record and starts therecording or reproduction, as the case may be. The record orreproduction will continue until the stylus arm hasy again reached theposition where the contact points bridge the contacts b3,

limi

lll@

whereupon the feed motor E and the feeding screws g" and 71,3 againstart, immediately stopping the phonograph motor through the withdrawalof the switch blade 7'2 from the contacts j', which takes place on theinitial movement of the puller carriage t, which is now n engagementwith the puller scre'w h3. Movement of the puller carriage 7b causes thepulling yoke h2 forcibly to withdraw the record from the supportingcylinder a into its compartment upon the holder C. On this returnmovement the carriage t overtakes the displaced pusher carriage g andforces the same with its connected 'pusher arm to its limit of travel,where, as has been described, the puller mechanism is disengaged and thepusher mechanism engaged with its corresponding screw.

Simultaneously, with the engagement of the pusher carriage with its feedscrew, the rotation of the latter is interrupted for an interval byenergization of the solenoid'e7, which clutches the driving gear e tothe holder driving' pinion c5, thereby to cause the holder to advanceone step to bring a fresh record adjacent to and in alinement with thesupporting cylinder a. The energization of the solenoid e7 is effectedin the following manner Referring more particularly to F igs. 2 and 10,the solenoid e7 is in series with the conductor Z leading from thebattery B, through the normally separated contacts Z, thence through theconductor Z2 to the contact pin fs'adapted to contact with the face ofthe finger f when the latter is drawn downwardly by the solenoid f?. Theother pole of the battery B is. connected, through the conductor Z3,with the pin f and therethrough with the finger f, so that the circuitis bridged at the contact pin f8 when Ithe fingery f contacts therewith.The contacts Z are carried by the bracket Z4, secured to the frame D,and the circuit through the solenoid e" may be completed by bridgingthese contacts, which is accomplished by the traveling contact Z5carried by the depending pusher carriage arm g1, the bridging of thesaid contacts occurring when the carriage is at its outward limit oftravel, as best shown inFig. 2. To permit the full completion of thecircuit and the energization of the solenoid e7, when the carriagereaches that position, and before opportunity is given, for backwardtravel, the other break in the said circuit at the contact pin f8 hasbeen previously closed by energization of the solenoid f". The latter(Figs. 2 and 10) is connected with one pole of the battery B through theconductor m, and with the other battery pole by a circuit which leadsfirst through the conducto-r m to the contacts m2 and thence to thebattery through the conductor m3. The two contacts m2 are also securedto the bracket Z4 and within the path of the traveling contact Z5, butslightly displaced from the contacts Z.

At the early part of the travel of the pusher carriage, when it isengaged in pushling the record on to the cylinder, the contact Z5bridgesthe contacts m2, closing the circuit of the solenoid f6 and thuspermits the spring f7 to force the lower part of the finger lever f uponthe contact pin f8 and to close the break in the clutch solenoid circuitat that point. VVhen, on subsequent carriage travel, the circuit of thesolenoid f is again broken, the released finger lever still remains incontact with the pin fs, the point of the linger restingl against thebot- .tom of the lug c6. After the feeding mechanism has carried therecord on to the cylinder and then withdrawn the same and finallydeposited it in the holder, it reaches the position shown in Fig. 2,where it then completes the clutch solenoid circuit by bridging thecontacts Z, immediately throwing.

viousl y engaged pusher carriage in motion,

to carry the new record on to the cylinder. This alternating operationof the phonograph mechanism and the feeding mechanisrn may continue aslong as desired or may he stopped at any time by opening the circuit atthe switch Ze.

I have herein shown the various electronnotive devices connected to abattery or batteries designated as B, but obviously any source ofelectro-motive fo-rce may be employed for this purpose and suchelectromotive devices obviously may have a common or separate sources ofelectro-motive force, as desired.

It will be observed that the feeding mechanisxn which has been'describedis independent of and may be readily applied to or withdrawn from thephonograph shown,

to permit the latter to be operated with or without the auxiliary feed.When it is desired to operate the phonograph without the feedingmechanism, the samemay be set in motion by short-circuiting 'thecontacts j through a controlling switch which may be provided for thatpurpose.l

Tt is to be understood that my invention is not confined to anyparticular type of phonograph, or other sound-reproducing or recordingmachine, nor to the details or relative arrangement of parts composingthe feeding mechanism, for these may undergo extensive modificationWithout departing from the spirit of my invention, and many changes,both in construction and in mode of operation, which I do not deem itnecessary to refer to, Will be suggested to those skilled in the art.Furthermore, as Will be readily understood by those skilled in the art,many obvious changes, unnecessary to refer to, may be made in theapplication of my invention to other types of machines or other purposesthan the specific one herein disclosed. It is also to be understood thatthe particular form of record holderhhere employed may be varied Widelyfrom that shown, to suit conditions of use, the form, capacity,construction and mode of operation of the holder herein shown beingsubmitted for illustrative purposes.
